AffineTransform on 2nd page

[useratnab <Ti...@gmx.net>]

Hello,

I'm trying to load a schematic xml and this works fine, until the point
where a second page with text output should be created. The Text is always
on different positions and sometimes turned around.

How can I specify a diffrebt transformation on a second PDF page:


private SchematicCanvas schem;

            FileOutputStream fos = new FileOutputStream(f);
            int width = 842;    // A4 in 72dpi
            int height = 595;
            
            pdf2D = new PDFDocumentGraphics2D( false, fos, width, height );
            Rectangle rb = schem.cont.getBounds();
   
            
            pdf2D.setGraphicContext(new GraphicContext());            
            
            double scale = (double)width / rb.width;
            double scale2 = (double)height / rb.height;
            double x0 = rb.x;
            double y1 = rb.y + rb.height;
            
            if (scale2 < scale) scale = scale2;
            scale *= 0.9;
            x0 -= (width / scale - rb.width) / 2.;
            y1 += (height / scale - rb.height) / 2.;
   
                     
            AffineTransform Tx = new AffineTransform( scale, 0, 0, scale,
                  -x0*scale* 300. / 72., y1*scale* 300. / 72.);
            
            pdf2D.setTransform(Tx);
            
            pdf2D.drawRect(rb.x, rb.y, rb.width, rb.height);            
                     
                        
            schem.cont.paint(pdf2D, null);
            
            
            pdf2D.nextPage();
            
                        
            pdf2D.setGraphicContext(new GraphicContext());
            pdf2D.setColor(Color.blue);
            
            AffineTransform old = pdf2D.getTransform();               
            
            AffineTransform Tx2 = new AffineTransform(new values);
            pdf2D.setTransform(Tx2);
            
            
            pdf2D.drawString("Hello World", 0, 0);
            
                        
            pdf2D.setTransform(old);

Sounds like a bug in PDFDocumentGraphics2D. Please note that not many
people will likely use this directly so it may not work as expected.
Help to fix these issues would be appreciated. I'm afraid I don't have
enough time to look into this at the moment.
